You may not want to use 11.1.1.2 anymore as it is not supported anymore by Oracle.

The following versions are recommended :

<li>Forms / Reports : 11.1.2
<li>Portal : 11.1.1.6

Oracle Portal 11.1.1.6 is available in the FMW 11.1.1.7 Media Pack which can be downloaded from [url edelivery.oracle.com]Oracle Software Cloud in a few days. Note that you still need to do a software only install for 11.1.1.2. After installation, you can patch the software tree with the 11.1.1.7 patch set to be at the latest version.

i want to publish the simple discoverer report through the weblogic server for testing purpose. i'm install the oracle database 11g, oracle RCU 11.1.1.6.0, weblogic server 10.3.6,
discoverer 11g. Is there any way to publish the report through the web. Reply me please ASAP.

I'm not sure whether that can be done through the Viewer as I never worked with Discoverer. Only know about the portlet option described in http://docs.oracle.com/cd/E23943_01/bi.1111/b40110/toc.htm. But that requires Oracle Portal. I leave it to others to comment on the first.

I believe you have to follow the same steps for publishing the discover report on weblogic server. i.e.
-create a particular report/graph/chart in discoverer and
-use Oracle portlet to publish the discoverer report/graph/chart on Oracle portal.
